43 * flash programming support for NXP LPC8xx,LPC1xxx,LPC4xxx,LP5410x and LPC2xxx devices.
45 * @todo Provide a way to update CCLK after declaring the flash bank. The value which is correct after chip reset will
46 * rarely still work right after the clocks switch to use the PLL (e.g. 4MHz --> 100 MHz).
49 * currently supported devices:
50 * variant 1 (lpc2000_v1):
58 * variant 2 (lpc2000_v2):
67 * - 176x (tested with LPC1768)
69 * - 178x (tested with LPC1788)
71 * lpc4000: (lpc1700's alias)
73 * - 408x (tested with LPC4088)
75 * lpc4300: (also available as lpc1800 - alias)
76 * - 43x2 | 3 | 5 | 7 (tested with LPC4337/LPC4357)
80 * - 810 | 1 | 2 (tested with LPC810/LPC811/LPC812)
81 * - 822 | 4 (tested with LPC824)
